HUGO TIRMAXN, OF CLEVELAND, OHIO, ASSIGNOR TO BENJAMIN PATTERSON, OF SAME PLACE.

TRACK-SANDING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 557,723, dated April 7, 1896.

Application filed December 7, 1895. Serial No. 571,349. (No model.)

T 0 aZZ 10700770 it 77mg concern:

Be it known that l, HUGO TIRMANN, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Track-Sanding Apparatus, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of various me chanical forms in which the principle of the invention may be used.

In said annexed drawings, Figure I represents a side elevation, part-lyin section, of my improved sanding device; Fig. II, an elevation of the valve-diaphragm; Fig. III, an elevation of the opposite side of said diaphragm, and Fig. IV a view of the valve-disk.

A casing A is formed with a general outline of a pipe-elbow and has a neck a, by means of which it is attached to and connected with the sandbox, and a neck a, by means of which it connects to a sand-pipe. The end of the limb having the neck a is closed by means of a cap 0?. A diaphragm B is secured in the horizontal portion of the casing, and said diaphragm has a small opening 1) in its upper portion and a large opening I) in its lower portion. A hood 19 extends from the upper edge of the diaphragm and covers the direct passage through the upper opening I), being curved to bulge toward the inlet-neck a. An air-blast pipe O is inserted through the wall of the casing to extend through the lower portion of the hood and has a nipple c, which projects downward in the space between the lower portion of the hood and the diaphragm. A valve-disk D has bearing against the diaphragm and is formed with an opening (Z, which may register either with the upper opening h in the diaphragm or with the larger opening Z) in the same when the disk is retated upon its center. The disk is connected at its center to a head D, which has rotary bearing in the horizontal portion of the casing, said valve-disk and head being connected by means of a stem (1.

The head D has a stem (P, which is journaled in the cap of the casing, and a spring (1 is coiled around said stem to force the head and the valve-disk toward the seat upon the diaphragm. A lever D is secured upon the outer end of the stem, outside of the cap, and the valve-disk may be rotated by means of said stem.

In practice when the inlet-neck a is connected to the sand-box and the outlet-neck a is connected to the sand-pipe sand will enter the vertical leg of the casing and rest there until the device is to be used. If the ordinary small quantity of sand is required upon the track, an air-blast is admitted through the air blast pipe, when said blast will create an upward eddy in the sand on account of the refleetion of the blast from the bottom of the easing, and sand will be thrown upward through the smaller upper opening in the diaphragm and the registering opening in the valve-disk into the horizontal chamber of the casing, whence it escapes into the sand-pipe. Then a larger quantity of sand is required,the valvedisk may be reversed, so as to bring its opening to correspond with the larger opening in the lower portion of the diaphragm, when the sand will flow out by its gravity from the sandbox through the easing into the sand-pipe. The curved hood over the upper opening serves to guide the sand through said opening when the air-blast is used and the lower opening in the diaphragm is closed. This device is particularly useful where sand-boxes are arranged one upon each side of the locomotive-boiler or where individual control of each sand-pipe is desired, as by the use of this device the sand supply to each set of drivers may be individually controlled, or the supply to both sides may be jointly controlled by connectin g the means which actuate the lever of each device. As the valve is'rotatable upon the face of the diaphragm no danger of 010g ging the valve exists in this device.

Other modes of applying the principle of my invention may be employed for the mode herein explained. Change may therefore be made as regards the mechanism thus disclosed, provided the principles of construction set forth, respectively, in the following claims are employed.

I therefore particularly point out and distinctly claim as my invention 1. In a track-sanding device, the combination of a casing provided with an inlet communicating with the sand-box and an outlet communicating with the sand -pipe, a diaphragm in said casing arranged between the inlet and outlet and provided with an openin g in its upper portion and with a hood which overhangs said opening on the side toward the inlet, and an air-blast pipe which enters said casing and has a downwardly-pointing nozzle within the lower portion of said overhanging hood, substantially as set forth.

2. In a track-sanding device, the combination of a casing provided with an inlet communicating with the sand-box and an outlet communicating with the sand-pipe, a diaphragm in said casing arranged between the HUGO TIRMANN. Vitnesses:
